Specification of Letters Patent N o. 723, dated May 4, 1838.

To all whom it may concern:

Be it known that I, JOSEPH S. IVES, of the city, county, and State ofNew York, have invented a new and useful Improvement in the Method ofApplying Coiled Metal Springs to House-Clocks, of which the following isa full and exact description.

The nature or" my invention consists in applying the springs A, Figure1, to the barrel arbors B on the outside of the front plate D, Figs. 2and 3, of the clock, instead of placing them on the inside of the clock,or between the plates as in the usual method. This I do by making asmall cylinder shaped block B, Fig. 1, of the same length as the widthof the spring, with a square hole through the center of it lengthwise,the same size as the square of the arbor E to which it is to be applied.This block which I term the arbor collet, has a hook or catch on theoutside of it which attaches to the inside end of the spring in theusual manner. This collet being placed on the arbor close without makingany alteration in them or taking them in pieces.

hat I claim as my invention and desire to secure by Letters Patent, is

The application of coiled metal springs in the manner described, to theoutside of the front plate of the clock.
